Even though Mupan was perplexed by Alex's words, he didn't let it affect him. He knew that it was bound to happen. Alex was the strongest person in the entire tribe. A person with his calibre asking to leave the tribe was natural. He has already grown beyond what the tribe could hold.
"Can I ask why?" Mupan asked.
Alex smiled and replied. "It's better if you don't." He didn't mean it negatively and Mupan could understand that.
The things he was going to do in the next few months could escalate beyond crazy. He didn't want the stone head tribe or anyone that was related to him to be affected by his action. The consequences of his actions were his own to bear.
"Sigh… Return safely." Mupan said before going back to his home. He had many things to think about.
Meanwhile, Alex went back to his mana training.
